Abstract (en)

[origin: US5928239A] A device and method for percutaneous surgical cavitation. The device includes an elongated shaft and cutting tip interconnected by a freely-rotating hinge. Upon rotation of the shaft to a sufficient velocity, the cutting tip will be deflected toward a position that is angularly offset from the shaft's access of rotation. The length of the cutting tip will determine the radius of the cavity being formed, which may be several times the radius of the shaft. The method of the present invention provides for formation of a cavity within a body through a small percutaneous access opening such that an enlarged cavity may be formed without an invasive access opening. The present invention also provides a method of percutaneous prophylactic replacement of osteoporotic bone wherein weakened bone material is removed from a cavity using only a needle-sized access opening. Strengthening bone replacement material, such as bone cement, can be injected into the cavity to provide reinforcement of weakened bone without invasive surgical access.
